Public Concerts with 2x 15 inch Lii full range drivers ?

[RaymondFromThePyrénéés]

My idea in the future is to offer concerts and to make people discover what I once discovered
with a simple one full range driver on a board that anyone can make themselves for little money.

I found a place, an association who offer concerts and theater
and the space measures 8 x16 meters (26x52 feet),
the ceiling is about 3 meters (10 feet) high.

The front, space behind the speakers could be either stonewall or a thick black curtain,
the side walls are of stone and cement, and the behind the chairs is a bar and an uneven space,
see images below.

My worries is , would I be able to get enough volume in such a space with a pair open baffle
Lii 15" speakers with my WiiM and the 3E 7A ?

And for the 2 subs if needed, I would need another pair of amplifiers.

I read that for baffles, a room with little absorbing materials have an advantage compared with
a room with lots of absorbing materials.

Perhaps this project in such a big space is impossible ?
Perhaps I need to find a smaller space ?

Thank you for any input.

Here is the space

It's a fun idea, I like it!))
AFAIR, Lii's volume is limited by Xmax (?). Plane pro full-range speakers are used in budget PA systems (in boxes, of course). I think it will be heard loudly enougy, so that the event is interesting.
Are there any subwoofers in this room used for concerts? But that would be a slightly different system than just a pair of full-range speakers.
I forgot the dimensions of your room, but I think you'd be interested in listening to it in a larger room.
In the photo, the room seems reverberant, is that true?

No way in hell. You’ll destroy those drivers in no time at all. Nevermind that those things beam quite a bit, so there will be a very narrow sweat spot.

Interesting. I'm curious about this:

My idea in the future is to offer concerts ....

Do you mean live music? What kind of music?

What's your budget?
The sensible thing to do would be to ask a professional PA technician what is required and how to get as good of sound with a PA rig/PA speakers for X $/€.
PA is made for this situation.

I don't know anything about running a live venue but the PA system itself should be one of the easiest things to set up vs. hiring staff, food and beverage, various permits, balancing a budget and so on.

Even though it's not intended to be a commercial enterprise (or is it?), it will cost money. Wouldn't you like to raise some money to at least cover some of your costs?

The little I know about open baffle speakers is that they often lack bass and high SPL capability. So maybe not the best choice for such an application. There are a few threads relating to PA type speakers here, which may be useful. Good quality second hand options are often available at reasonable prices.
Personally I am a big fan of the pro-audio Tannoy coaxials.

... Gotta love his extra large buffet plate too.

[Ropeburn]

Open baffle speakers with their serious lack of bass and low efficiency, a mere 2x200W amplifier not made for high continuous load, in such a large space.

No way that's going to work. Everything about this system is the exact opposite of suitable for the purpose.

I'd rather get cheap PA speakers and a high power pro amp like a Crown or Behringer. You need cone area, efficiency and power all at once to move all that air, especially when lots of people come in and act as fleshy absorbers. Essentially what you want here is a small club system. You can also rent them and get professional advice in the process. Try out and see what works, before you buy anything.

 

[Devnull]

How would you fly the speaker? Actually get the sound above the crowd not into the front row. Why would you use a wiim? A concert venue uses pro sound amps for a reason, easy to replace or substitute when something fails. Not if something fails, when it fails.

Ask yourself one question - if this made sense wouldn't you have seen it implemented already?

 

[DanielT]

Here is the space

By the way. It seems that there are already PA speakers in that venue. :

Aren't they included if you rent that venue?

Please note, I'm not negative. On the contrary, I applaud your ambitions. I'm mostly curious about the whole thing.

Same here. The whole thing even makes me a lil jealous in the good sense, it's something I'd love to do myself. Looking forward to seeing what becomes of this. @OP please keep us updated.

I'm curious about your statement regarding these speakers beaming. Is it based on testing, personal experience, or just belief?

 

[RaymondFromThePyrénéés]

Whaoo, that was a lot of reactions to this project.

Hearing, Reading you all,
I think that I would have to find a much smaller
room and invite like say about 7-8 persons.

Bass should not be a problem since I intended to add
2 subs apart from the 2 open baffles.

Should the subs be open baffle as well, that is a question...

Now to the sweet spot, it is of course impossible to arrange
for everyone sits ON the sweet spot but knowing that people
who come are not experts like you here, perhaps not sitting
exactly ON the sweet spot would be ok ? I wonder ?

My idea is to create an association, a sort of HiFi Club to
share these possibilities about high-end music for a low price
that is indeed possible today, especially with open baffle speakers.
This club could possibly also evolve to construction projects.

This is the website that inspires me the most :

They are 15” single woofer speakers, so, yeah they will beam. No amount of wizzer cones will prevent this.

Well if your intention is demonstrating these particular speakers, and similar ones in the future, then indeed the best option is to find a fitting room for them.

You'll be entertaining guests though and that place there looks nice for that with the bar an all. Is there a smaller room there by any chance? One you could use for listening purposes? Then the seperate bar space could work nicely like a sort of chillout area in a nightclub, where people can relax and chatter and give their ears a little break.

These speakers are only “high-end” in terms of silly, niche, overhyped vintage inspired products. Objectively, these make for rather poor speakers. And they aren’t exactly low-price either. Fame 12-250 TC will be below €100.

Aha, now I get it. Similar to this:

I listened to open baffles with subs a few years ago, that sound was nothing short of high fidelity, I would say rather pretty amazing sound. Not to the taste of everyone and perhaps not for all sorts of music. The budget would be around 1500-2000 plus a pair of subs for the same price I would think.

yes, perhaps begin with a couple of people at my own home to see...
